Mouthpiece Protectors – Protect your mouthpiece and extend its life with a mouthpiece protector (2/pack). These mouthpiece protectors were originally made for the AirStreams and are now used by many pipers on all different types of mouthpieces. The soft rubber helps you protect the blowpipe and your teeth. It may be necessary to put a small amount of lubricant inside the rubber to make it slide on easier. (Mouthpiece shown is not included.)
